'Elie-Cani members 8' and 9 aie lisposed to operate iii opposite iireotions, ami eneaeh with a plurality or" cam blocks 13 which are Constructed complementary to the cam surfaces. @il the iueiiihers 8 and 9, .vlie'rebv to be :assembled with said meu'ibers after the manner illustratedy in Fig. 1, The several iam liloels series to either sifle of al, plate 1.1, which is centrally aperturedat 15 to receive the piu 10, and has a plurality of radiallyv disposed .slots 1i; that receive projectingY pius 17 ou liolrl sairl emu blocks in relative spaced relation aud permit ot' their radial uil-veulent uucler the ariou of the cam members 7 aufl 8.

A pziii" of si lit rings or liaiuls 1R aiul 19 are iuouuteil ou the several raui hloellrs 13, aiul are operzihle to resist the oulvv'ari'l movement 'of said eaux lileekst1 and iu this ixiauiiei serve to absorb the shock transmitted through the arms il azul l. A seeoiul resilient aud split ring or bami 20 eiu'ireles the tivo rings 18 aiul 151 and the peripheral retaining plate 1l, and has for ts purpose to auguieut the resistauee to the uoveiuent oi the Cam blocks 13 liv the resillientr riugs 1S :incl 19.

rl"he several resilient rings 13. 19 aud 20 :ire of redueing thirliuess toward the split iliortiou. as clearly illustrated .iu Figs. 1 and 2, aud tlieclividetl portions of s; ill riuggjs are (li sh oivn iu saiil figures.

lu operation, lthe tivo arms and l, ivhen move( tmvard eaeh other, act through one of the cani members (7 or 8), 'to move its respective series el: eam blocks 13, and these 'in turn ect against the combined .resistance 13 are disposeflu tivov s'poseil iu opposed relationl` as likewise- Cir offered by the inner and onter resilient bands, and thus cushion or absorb the shook transmitted. And' in like manner, when the arms 5l and l are moved in opposite directions, the other cam member acts on its respective series of eam blocks 13., which action is in turn resisted by the outer and one oit' the inner bands.

t isY obvious that those skilled in the art may vary the details or' construction and arrangement of' parts Without departing from the spirit-of our invention, and therefore We do not Wish to be limited to such features except as may be required by the claims. v

.We claim:

l. ln a shock absorber the combination oi two relatively rotatable members providing a easing; opposite and annularly disposed cam elements mounted on. said members respectively; radially movable members assooiated with said cam elements and operable thereby.; and a resistant means opposed to said cam actuated members, substantially as described.

2. ln a shock absorber the Combination of two relativel rotatable members oroyidino' l m a easing; oppositely disposed eam elements mounted on said members respectively; a retaining member; members Connected to said retaining member engaging with said cani elements and operable thereby; and a resistant means surrounding and adapted to oppose said cam actuated members, substantially as described.

ln'a shock absorber the" combination of two relatively rotatable members providing a easing; oppositely disposed cam elements mounted on said members respeetiv'ely; a member located between ,said opposed earn elements; a plurality of cam blocks retained in spaced relation by said'meulber, 'engaging with said cam elements and operable thereby; and a resilient band surrounding and adapted to oppose said Cani blocks, substantially as described.

Il. ln a shook absorber the combination of tvo relatively rotatable members proyjidingv a casing; oppositely disposed cam elements having looking' engagement With said members respeelirely; plate located between said opposed cam elements; a plu u cam blocks mounted to bave rai: al movement on said plate; resilient means sur rounding` and adapted to oppose said earn blocks; and. a second opposing reeilient means surrounding the lirst named resilient means, sul'lstantially as described.

ity oi" ln a shook absorber the mimbination oit two relatively rotatable members proyit a casing; opposilely disposed earn elementsl having lockingl engagement with said inem- -bers respectively; a plate located between said opposed cam elements and having radially disposed slots; a plurality cam blocks engaging the opposed 'cam elements, respectively, and havingpins in said slots; resilient bands surrounding said earn blocks, respectively, and adapted to oppose said cam. blocks; and a. resilient band surrounding and adapted to impose said rcsilient bands, substantially as described.

G. ln a shook absorberl the. combination oi' two relatively rotatable members providing a easing` and having,` apertures :forming locl ing means; a pair of members homing;1 cam elements, and portions fitting within said apertures and having looking: engagement with said looking` means; a. pin passing through said eam members and providin a pivot; a plate mounted on said pivot pin between said cam members; a. plurality et cam, bloelrs loosely connected to said plate and located on either side o said plate and in Contact with said Cam elements; pair of split rings mounted on said cam blocks, res spectively, and adapted to loppose the same; and a single split rino; mounted on said pair oit resilient rings and adapted to oppose the same, substantially as described.

ln testimony whereof, our tures, in presence of two witnesses. Y
